Obtaining installation media
It's time to get started! If you've decided to utilize a physical server, desktop, laptop, 
or VM as your test server, then you'll need to go through the installation process to 
set up Ubuntu. Don't worry—it's very easy to do and is made even easier in Ubuntu 
20.04 as there are fewer overall steps in the process. If you've instead opted to use a 
VPS or Raspberry Pi, you won't need to go through this process, as VPS providers 
do this for you and Raspberry Pi has a different setup method altogether (we'll cover 
this later in the chapter, in the 
Installing Ubuntu on a Raspberry Pi
 section).
Assuming that you've decided to use a device that does require going through the 
installer, we'll need to download Ubuntu Server and then create bootable installation 
media to install it. How you do this largely depends on your hardware. Does your 
device have an optical drive? Is it able to boot from USB? Refer to the documentation 
for your device to find out.
It's recommended to utilize a flash drive for the installation if you can, preferably one 
that uses USB 3.0 or higher since you'd benefit from its faster speed compared to USB 
2.0. The reason for the preference toward using a flash drive is due to the fact that 
they are typically faster than a DVD.
